Abstract: Based on the previous studies on the subject and by researching on the test of a 1/2-scaled combinational multi-ribbed composite wall under low-cyclic reversed horizontal load in contrast with a standard wall,we are devoted to fulfilling the following points on the combinational wall in this paper: studying the main failure patterns;discussing the mechanical behaviors such as bearing capacity,hysteretic loop and so on,finally giving the formulas of rigidity and shear-bearing capacity.Experiment and theoretic research show: that the value of the shear-bearing capacity formula approximates to the experimental result,and can be applied to practical projects.
